Tantra does work.
Saw Trish in the Annex about three times several years ago http://www.thesacredspot.com or (416) 763-8523. I was skeptical but the options available to me at the time were limited so I figured why not? First two visits were essentially prolonged HJ's but the last visit was incredible!
I had opted for the session that included a bath ceremony (she sits in the tub with you, behind you, and gives you a HJ), DIGITS, and DFK and HJ on a bed afterwards. Whilst I was following her instructions on proper breathing technique as she was giving me a HJ and PM, I felt a wave of heat rise from my crotch all the way up to the top of my head. I then had what I felt were ten or more super intense orgasms, one right after the next. When it was all over I was completely spent and awed to find out that I did not cum, not a single drop. Trish explained that I had just experienced a "full body orgasm". I tried getting up by was extremely light headed and she advised me to lay back down and relax for several minutes. Not sure if she is still around but it was one of the most intense experiences I've had and sold me onto Tantra.
